' Ion CAN.

Application filed December This invention relates to ice cans of. the high I pressure type, one of the objects'being to provide a simpleand elficient structure.havlng means combined therewith whereby air can 3e forced to the bottom of the can so to agitate the water while freezin Various means for this purpose have been. devised heretofore but generally they have been located inside o'fithe. can wherethey are likely to become distorted by the removal of the ice and have caused undesirable depressions or the like in the cake of ice produced.

it is an object of the present invention to provide a means located within one of. the seams of the can whereby the air will be con ducted to the bottom of the can, the resultant cake of ice being free of any grooves or recesses and there being no parts likely to be come bent or oth erwiso injured by the removal of the ice from the can. A further object is to provide acan formed of few parts and the. parts of which canbe assembled readily. l

With the foregoing and other ob]ec ts in view which will appear as the descriptionproceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described I and claimed, it being understood that changes in the precise embodiment otthe invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

in the accompanying drawings the preferred form of? the invention has been shown.

In said drawings, l iguro '1 is a perspective view of a can constructed in accordance with the present 111- vention. Figure Qis a side elevation thereoi one or the l ips o't'a seam in the can being removed to show'the air passage. 1 Figure?) is a top plan View of the can; Referring to the figures by characters of reference 1, designates a can of'the usual size and proportions thereheing a seam along one corner portion oi the can formed by a flange 2 which laps'one side wall of the can. Ordinarily these lapping portions or flanges have been attached directly to the Walls of the cans by means of rivets. {In the present instance the flange 2 of one of the seamsof the can is spaced from the wall of'the can l by spacing strips 3 and the rivets a used for holding the lapping portions of the can together are extended through the spacing of waved as shown. ment s so obvious that it is not deemed neces- 5, 1925 Serial No; 73,495. 1

strips so as to secure them in place. In the structure illustrated the r1vets extending through one of the spacing strips are staggered'with reference to the rivets extending through the other spacing strip and those edges of the strips which are nearest each other are serra ed so as to form between them a waved passage 5 which extends from the top of thecan. to a point adjacent the bottom thereof. The strips 3 come together at the bottom of the can so as to close the lower end of the passage An aperture 6 is formed in the wall of the can and communicates with the lower end portion 01 the passage 5.

It will be obvious from the foregoing that when air is directed under pressure into the upper end of the passage 5 it will flow down- Obviously, if desired, the strips 3 can be v formed with straight edgesinstead oi" scrrated edges. In that event the passage would be st *aight irom top to bottom instead This modified arrangee sary to show or describe the same in detail.

What is claimed is:

1.- An ice can of the high pressure type having flat lapping portions extending longitudinally thereof outside of thecan, spacing elements separate from and located between the lapping portions iormingan air pasage therebetween within the outer por- ,tion of one wall of the can, there being an air inlet at the upper end of the PZXSSQLQQ and an 1 outlet connecting the lower end of the passage with the bottom portion of the can and securing means extending through the lapping portions andthe spacing means for holding them clamped together.

2. An ice can otthe high pressure type including fiat lapping portions extending from the top 'to the bottom-thereof outside the can, said portions being integral w th two of the walls of the can respectively, spacing elements separate from and interposed, be-

tween said lappingportions and contacting at their lower ends, said spacing portions being spaced apart for the greater portion of their length to provide an air passage with in the outer portion of one wall of the can and open at one end; there being an aperture for maintaining communication between the other end of the passage and the bottom por tion of the can, and securing means eXten din gthrough the lapping ing means for holding them clamped together an d soaking the passage between its inlet and outlet. 7 I

3. An ice can of the h1gh pressure type 111- ohiding a flat longitudinal flange upon one wall of the can lapping the outer face 0t another Wall thereof, spacing strips separate from and interposed between said flange and the Wall lapped thereby, said strips eooperet-e in" With the flan e and well to "form an air b a I, passage Within the outer port-ion or one Well portions and the spac-- of the can and open at its upper end and closed. at its lower end, there being an aperture for establishing communication between said passage and the iower portion of the can, and securing means extending through the tapping port-ions and the spacing strips for holding them ohui'iped together and for sealing the air passage except at its open end and at the aperture.

In testimony that I claim the foregoing as my own, 1 have hereto eiiixed my signature.
